It's very hard to find, nor easy to make, a perfect hair model.   My compromise is that I spend my money choosing hair style over texture, then I borrow Koz's hair texture, tone down the highlight and paste it over the poor texture map of the stylish hair.

AprilYSH sells a lot of cool-styled hair at DAZ3D, although most of the textures look fake, they can be modified easily with a graphic program to fit your needs.

I think before we find a perfect hair, that can be a nice compromise, plus a bit of post work.
